HEAD BAND Filed April 28, 1941 M? /'/\,M ATTORNEY Patented Aug. 31, 1943 UNITED STATES PATENT OFFICE HEADBAND Application April 28, 1941, Serial No. 390,726

Claims.

The present invention relates to head-bands, and more particularly to head-bands for supporting welding hoods.

An object of the invention is to provide a new and improved head-band of the above-described character.

Other and further objects will be explained hereinafter and will be particularly pointed out in the appended claims.

The invention will now be more fully explained in connection with the accompanying drawing, in which Fig. 1 is a perspective of a head-support for a welding hood: Fig. 2 is a broken plan of a preferred head-band ribbon; Fig. 3 is a vertical section taken upon the line 3-3 of Fig. 1; and Fig. 4 is a horizontal section taken upon the line 4-4 of Fig. 3, looking downward, in the direction of the arrows.

Diagonally opposite corners 2 and 4 of the head-band ribbon 6 are each provided with an extension 8 and I0, respectively, of smaller width than the body portion of the ribbon. The respective outer boundaries l2 and I4 of the extensions 8 and iii are shown as continuations of the outer boundaries i6 and I8 of the body portion 6 oi. the ribbon. At its free end 28 the extension 8 is provided with a portion 22 projecting from its inner boundary 24 in a direction away from its outer boundary I2. Extension I0 is similarly provided at its free end 26 with a portion 28 projecting from its inner boundary 30 in a direction away from its outer boundary l4. The projections 22 and 28 are of substantially equal length and the width of the body portion of the ribbon 6 is shown as equal to the combined width of the two extensions 8 and I0 and the length of either projection 22 or 28.

The ribbon 6 may be bent into the form of a split head-band, as shown in Fig. 1. If the corner 4 be taken as the upper corner of one end of the split head-band, the corner 2 will be the lower corner of the other end thereof. The extensions in and I2 may then be disposed in lapping relation side by side along their width dimension, as shown more particularly in Figs. 4 and 5, enclosed in a flattened sleeve 32, disposed at the rear side of the head-band with the projection 22 projecting toward the extension In and the projection 28 projecting toward the extension 8.

Owing to the fact that the width of the body portion of the ribbon 6 is equal to the combined width of the two extensions 8 and i0 and the length of either projection 22 or 28, the projection of each extension will engage the other extension when the extensions are overlapped, with the outer boundary of each extension alined with the outer boundary of the body portion of the ribbon adjacent to the other extension, as clearly shown in Fig. 3.

The sleeve 32 is shown as of slightly greater width than the width of the body portion of the band ribbon 6, so as to receive the extensions 8 and I0 therein in longitudinally adjustable lapping relation, with the extension I0 above the extension 8, and with the projection 22 engaging the extension l0 and the projection 28 engaging the extension 8. Relative adjustment of the extensions 8 and I0 longitudinally back and forth in the sleeve 32 results in adjustment of the size of the head-band, to provide for different sizes of heads of different welders.

A screw-threaded member 34 extends through alined openings 36 and 38 in opposite walls 40 and 42 of the sleeve 32, and between the extensions 8 and i0 and the projections 22 and 28. A head 44 of the screw-threaded member 34 engages the wall 40 of the sleeve 32 and a nut 46, threaded upon the screw-threaded member 34, engages the wall 42. By threading the nut 46 into tight engagement with the wall 42, the sleeve 32 will become clamped against the extensions 8 and 10 to secure the extensions in adjusted position. The projections 22 and 28, by engaging the screw-threaded member 34 in the extreme limits of adjustment, prevent the extensions 8 and Hi from slipping out of the sleeve 32.

The head-band is shown supported by a headstrap 48. The head-strap 48 is shown provided with looped ends 50 and 52, to which the headband is intermediately secured by rivets 54. The looped ends are held in place by means of rivets 56.

The head-band need not be in one piece. The same adjustment may be provided in a head-band comprising two separate ribbons to the left of the looped ends 50 and 52, as viewed in Fig. 1.

One of the difliculties with present-day supports for welding hoods is that the joint between the ends of the supporting head-bands is so constructed that it catches in the wearers hair. The present invention overcomes this diiiiculty. A head-band is thus provided that will not catch in the hair, and that is provided with novel mechanism for adjusting the head-band.

The parts may be made of any suitable material. The sleeve 32, for example, may be of metal or fiber. The head-band ribbon 6 and the head-strap 48 may be constituted of fiber.

Modifications will occur to persons skilled in the art, and all such are considered to fall within the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A split head-band the upper corner of one end of which and the lower corner of the other end of which are each provided with an extension of smaller width than the width of the body portion of the head-band, the outer boundaries of the respective extensions being continuations of the respective outer boundaries of the body portion of the head-band, the extensions being disposed in lapping relation side by side along their width dimension and being relatively adjustable longitudinally to permit adjustment of the size of the head-band, a sleeve enclosing the lapping extensions, and means for clamping the sleeve against the extensions to secure the extensions in adjusted position.

2. A split head-band the upper corner of one end of which and the lower corner of the other end of which are each provided with an extension of smaller width than the width of the body portion of the head-band, the outer boundaries of the respective extensions being continuations of the respective outer boundaries of the body portion of the head-band, the extensions being disposed in lapping relation side by side along their width dimension and being relatively adjustable longitudinally to permit adjustment of the size of the head-band, a sleeve enclosing the lapping extensions, and means disposed between the extensions and engaging the sleeve to clamp the sleeve against the extensions to secure the extensions in adjusted position.

3. A split head-band the upper corner of one end of which and the lower corner of the other end of which are each provided with an extension of smaller width than the width of the body portion of the head-band, the outer boundaries of the respective extensions being continuations of the respective outer boundaries of the body portion of the head-band, the extensions being disposed in lapping relation side by side along their width dimensions and being relatively adjustable longitudinally to permit adjustment of the size of the head-band, the extensions each being provided at its free end with a portion projecting toward the other extension, the projections being of substantially equal length, the combined width of the extensions and the length of one of the projections being substantially the same as the width of the body portion of the head-band, a sleeve of slightly greater width than the width of the body portion of the head-band enclosing the lapping extensions, a screw-threaded member disposed between the extensions having a head engaging a wall of the sleeve, and a nut threaded upon th screwthreaded member and engaging another wall of the sleeve to clamp the sleeve against the extensions to secure the extensions in adjusted position.

4. A head-band ribbon diagonally opposite corners of which are each provided with an extension of smaller width than the width of the body portion of the ribbon, the outer boundaries of the respective extensions being continuations of the respective outer boundaries of the body portion of the ribbon, the extensions each being provided at its free end with a portion projecting from its inner boundary in a direction away from its outer boundary, the extensions being disposed in lapping relation side by side along their width dimension, the combined width of the extensions and the length of one of the projections being substantially the same as the width of the body portion of the ribbon, a sleeve of slightly greater width than the width of the body portion of the ribbon enclosing the lapping extensions, the sleeve having oppositely disposed side walls, the extensions being individually adjustable longitudinally in the sleeve to permit adjustment of the size of the head-band, a screwthreaded member disposed freely between the extensions having a head engaging one of the side walls of the sleeve, and a nut threaded upon the screw-threaded member and engaging the other side wall of the sleeve to clasp the sleeve against the extensions to secure the extensions in their individually adjusted positions in the sleeve.

5. A split head-band the upper corner of one end of which and the lower corner of the other end of which are each provided with an extension of smaller width than the Width of the body portion of the head-band, the outer boundaries of the respective extensions being continuations of the respective outer boundaries of the body portion of the head-band, the extensions being disposed in lapping relation side by side along their width dimension and being relative- 1y adjustable longitudinally to permit adjustment of the size of the head-band, the extensions each being provided at its free end with a portion projecting toward the other extension, the projections being of substantially equal length, the combined width of the extensions and the length of one of the projections being substantially the same as the width of the body portion of the head-band in order that when the extensions are engaged in the said lapping relation the projection on each extension may engage the other extension with the outer boundary of each extension alined with the outer boundary of the body portion adjacent to the other extension, and means securing the extensions in adjusted position.
